Well now, lets see what we have here. Generally a clean chassis with no signs of rust. Some dust and a couple of cob webs but looks good. Some tubes have been changed over the years as three Zenith tubes were replaced with Sylvania types. The Selenium rectifier is going to have to be replaced with a modern and safer diode and the pictures show all the waxy paper caps to be replaced on the under side.

Looks like it's in good condition. Is it a power transformerless design? Just curious.

  Are you sure? yes | no

Thanks. Yup, mains go straight to the selenium rectifier, oh well. It has been years since I have worked with tube circuits ;-)
